McLaren MP4-23 - reduced sidepod inlets 20 October 2008

As in Belgium, in China the cross-sectional area of the McLaren's sidepod inlets was reduced, decreasing cooling capacity but increasing aero efficiency. At Spa the low ambient temperatures made this change feasible. In Shanghai it was possible - albeit to a slightly lesser degree - thanks to the cooling provided by the two long, high-speed straights. A specially profiled 'insert' was added to the bottom of the inlet, making the inlet smaller. This cuts drag and turbulence immediately in front of the sidepod, aiding the car's top-end performance on those long straights.
